The information in +this chapter was obtained using Release 3.2.1. + +@section Introduction + +The timing data for the i960CA version of RTEMS is +provided along with the target dependent aspects concerning the +gathering of the timing data. The hardware platform used to +gather the times is described to give the reader a better +understanding of each directive time provided. Also, provided +is a description of the interrupt latency and the context +switch times as they pertain to the i960CA version of RTEMS. + +@section Hardware Platform + +All times reported except for the maximum period +interrupts are disabled by RTEMS were measured using a Cyclone +Microsystems CVME961 board. The CVME961 is a 33 Mhz board with +dynamic RAM which has two wait state dynamic memory (four CPU +cycles) for read accesses and one wait state (two CPU cycles) +for write accesses. The Z8536 on a SQUALL SQSIO4 mezzanine +board was used to measure elapsed time with one-half microsecond +resolution. All sources of hardware interrupts are disabled, +although the interrupt level of the i960CA allows all interrupts. + +The maximum interrupt disable period was measured by +summing the number of CPU cycles required by each assembly +language instruction executed while interrupts were disabled. +Zero wait state memory was assumed. The total CPU cycles +executed with interrupts disabled, including the instructions to +disable and enable interrupts, was divided by 33 to simulate a +i960CA executing at 33 Mhz with zero wait states. + +@section Interrupt Latency + +The maximum period with interrupts disabled within +RTEMS is less than +2.5 microseconds including the instructions +which disable and re-enable interrupts. The time required for +the i960CA to generate an interrupt using the sysctl +instruction, vectoring to an interrupt handler, and for the +RTEMS entry overhead before invoking the user's interrupt +handler are a total of 37 +microseconds. These combine to yield +a worst case interrupt latency of less than +2.5 + 37 +microseconds. [NOTE: The maximum period with interrupts +disabled within RTEMS was last calculated for Release +3.2.1.] + +It should be noted again that the maximum period with +interrupts disabled within RTEMS is hand-timed. The interrupt +vector and entry overhead time was generated on the Cyclone +CVME961 benchmark platform using the sysctl instruction as the +interrupt source. + +@section Context Switch + +The RTEMS processor context switch time is 1 +microseconds on the Cyclone CVME961 benchmark platform. This +time represents the raw context switch time with no user +extensions configured. Additional execution time is required +when a TSWITCH user extension is configured. The use of the +TSWITCH extension is application dependent. Thus, its execution +time is not considered part of the base context switch time. + +The CVME961 has no hardware floating point capability +and floating point tasks are not supported. + +The following table summarizes the context switch +times for the CVME961 benchmark platform: + +@c ****** This comment is here to remind you not to edit the timetbl.t +@c ****** in any directory but common. +@c +@c Time Table Template +@c +@c COPYRIGHT (c) 1988-1999. +@c On-Line Applications Research Corporation (OAR). +@c All rights reserved. +@c +@c $Id$ +@c + +@ifset use-tex +@sp 1 +@tex +\centerline{\vbox{\offinterlineskip\halign{ +\span\rtemstimetable +\rtemsonecase{No Floating Point Contexts}{1} +\rtemsdirective{Floating Point Contexts} +\rtemscase{restore first FP task}{2} +\rtemscase{save initialized, restore initialized}{3} +\rtemscase{save idle, restore initialized}{4} +\rtemscase{save idle, restore idle}{5} +\rtemsendtimetable +}}\hfil} +@end tex +@end ifset + +@ifset use-ascii +@ifinfo +@itemize @bullet +@item No Floating Point Contexts +@itemize -
